It's TxTextControl there is an evalation copy available, http://www.textcontrol.com/downloads

What I think is happening is that VFP does not like 3 values in the property assignment, so calling an ActiveX property like this
control.CellText(1,1)="Hello"
is fine, but
control.CellText(LnHandle,1,1)="Hello"
is not.

I guess it sort of makes sense to VFP, I just can't think of a workaround.
